  What Students Learn:
Maintenance work involves hoisting or lifting and moving machines, and other heavy loads. A new machine may have to be moved in, and installed on its foundation; a broken machine may have to be hoisted and taken to the maintenance area for repair. For such work, trades people will need hoisting equipment, plus certain accessories, such as rope and chain slings. Therefore, it is important for trainees to be familiar with the common types of hoisting equipment and slings.

In maintenance work, you will often have to remove parts, such as gears and bearings, from an assembly. Pullers are very useful tools for such purposes. The commonly used pullers are of the jaw and push types.

When a student completes this study unit, he and she will be able to:
  • Identify the many forms of jacks and hoists.
  • Safely operate jacks and hoists.
  • Understand the construction details of fiber ropes, wire ropes, and chains.
  • Properly use and maintain fiber-rope, wire-rope, and chain slings.
  • Properly use jaw and push pullers.
